A current-compensated inductor for filtering interference signals which are transmitted between two high-voltage components of a high-voltage on-board electrical system of a motor vehicle, includes a toroidal, in particular circular ring-shaped or oval ring-shaped, magnet core which surrounds an inner opening, and has at least two busbars for electrically connecting the two high-voltage components. The busbars are routed axially through the inner opening of the magnet core and are arranged at a distance from one another in the inner opening so as to form an air gap. An inner side of the magnet core, which inner side faces the inner opening, and regions of outer sides of the busbars, which regions face the inner side of the magnet core, have shapes which correspond to one another.

A rotor for an electric motor includes an even number n of pole pairs arranged on a rotor body with rotor windings connected in series between two electrical connections to supply or conduct away current through the rotor windings. The series circuit has a first section including n/2 rotor windings arranged first in the series circuit, and a second section including n/2 rotor windings and arranged upstream of the second electrical connection. During application of a direct-current voltage between the two connections in each of the rotor windings of the first section, the radial component of the direct-current flow in the series circuit extends through the entire respective rotor winding, from an outer side to an inner side of the rotor winding, and in each of the rotor windings of the second section, in reverse, from an outer side to an inner side of the rotor winding.

A control method and a switching device are provided for a separately excited synchronous machine as a drive in a hybrid or electric vehicle. The switching device converts and/or distributes electrical energy within the vehicle, in particular the hybrid or electric vehicle, wherein an asymmetric full bridge is provided, in the bridge branch of which a rotor of an SSM is arranged. Switches are provided in the asymmetric full bridge in order to provide a pulse width modulation corresponding to a desired motor rotational speed and power of the SSM. The device is characterized in that it has a short-circuit branch extending in parallel with the bridge branch of the asymmetric full bridge, by which short-circuit branch the rotor of the SSM is able to be short-circuited.

A drive arrangement for an electrically driven vehicle includes an electric motor that is configured to accelerate the vehicle, the electric motor has a rotor, which is arranged inside a stator having stator windings and is arranged on a rotor shaft. The drive arrangement also includes a drive shaft coupled to a drive wheel of the vehicle, and a shaft coupling that transmits torque output by the rotor shaft such that said torque is conducted to the drive shaft, wherein the shaft coupling has a torque receiving element that receives the torque output by the electric motor, and a torque output element that is mechanically coupled to the torque receiving element and outputs the torque in a direction of the drive shaft. An electrically insulating grease is arranged between the torque receiving element and the torque output element.

A device is for adjusting guide blades of a gas turbine. The guide blades are each connected to an adjusting ring via an adjusting lever, so as to be able to swivel, a first end of the, or each, adjusting lever engaging with the adjusting ring, and a second end of the, or each, adjusting lever, opposite to the first end, engaging with an end of a shaft or shank of the respective guide blade. The adjusting ring is assigned a rotor of a torque motor, a stator of the torque motor concentrically surrounding the rotor of the torque motor.

In a transverse flux machine, the rotor has multiple permanent magnet rings that are arranged axially in proximity to one another. The stator surrounds the rotor concentrically in at least some sections, forming an air gap. The stator has multiple stator coils oriented coaxially with the permanent magnet rings and the stator coil has two terminals. An active reactive power source to be controlled has two terminals for each stator coil, the respective stator coil being connected to each. In the event of a fault incident in one of the stator coils, a monitoring arrangement supplies triggering signals for the active reactive power source so that the two terminals of the respective stator coil are interconnected with a low resistance.
